Patent DE-4122370-A1 (DE)
Inventor: MARKWARDT KLAUS DIPL ING
IPC: A22C15/00
Filed: 1991-07-05
Abstract: A process and device are disclosed for hanging sausage chains in loops. Successive hooks (10) that turn in an essentially horizontal transport plane catch at a transfer point an approximately vertical twist point (6) located between two sections of the sausage chain (5) and advance out of a vertical line that crosses the transfer point, optionally cyclically. The distance between the two successive twist points of each section in the reception areas (12) of the hooks in the direction of transport is set at least in the area of the transfer point so as to be so large that each naturally curved sausage takes in the corresponding section of the sausage chain located between two hooks, a rotation-stable position with respect to the straight line (rotation axis) that links the two twist points that delimit the sausage. Then the twist point at the front end of the section, seen in the direction of transport, is rotated around an approximately vertical axis in a predetermined direction of rotation over an angle in the order of 90 DEG .
